| 20110295225 | METHOD FOR THE PREPARATION OF A HIGH-TEMPERATURE STABLE OXYGEN-CARRIER-CONTAINING PHARMACEUTICAL COMPOSITION AND THE USE THEREOF - A high temperature-stable and highly purified α-α cross-linked tetrameric hemoglobin suitable for use in mammals without causing renal injury and vasoconstriction is provided. The dimeric form of hemoglobin is degenerated and purification processes are performed on red blood cells obtained from whole blood. Controlled hypotonic lysis in an instant cytolysis apparatus prevents the lysis of white blood cells. Nucleic acids from white blood cells and the phospholipids impurities are not detected. The blocking of reactive sulfhydryl groups in hemoglobin by a sulfhydryl reagent is performed in an oxygenated environment. Flowthrough column chromatography is used to remove different plasma protein impurities. N-acetyl cysteine is added to the α-α cross-linked tetrameric hemoglobin solution to maintain a low level of met-hemoglobin. The stabilized hemoglobin is preserved in an infusion bag with aluminum overwrap to prevent formation of inactive met-hemoglobin from oxygen intrusion. The product finds use in tissue oxygenation and cancer treatment. | 12-01-2011 |
| 20110319332 | TREATMENT METHODS USING A HEAT STABLE OXYGEN CARRIER-CONTAINING PHARMACEUTICAL COMPOSITION - A highly purified and heat stable cross-linked nonpolymeric tetrameric hemoglobin suitable for use in mammals without causing renal injury and vasoconstriction is provided. A high temperature and short time (HTST) heat processing step is performed to remove undesired dimeric form of hemoglobin, uncross-linked tetrameric hemoglobin, and plasma protein impurities effectively. Addition of N-acetyl cysteine after heat treatment and optionally before heat treatment maintains a low level of met-hemoglobin. The heat stable cross-linked tetrameric hemoglobin can improve and prolong oxygenation in normal and hypoxic tissue. In another aspect, the product is used in the treatment of various types of cancer such as leukemia, colorectal cancer, lung cancer, breast cancer, liver cancer, nasopharyngeal carcinoma and esophageal cancer. The inventive tetrameric hemoglobin can also be used to prevent tumor metastasis and recurrence following surgical tumor excision. Further the inventive tetrameric hemoglobin can be administered to patients prior to chemotherapy and radiation treatment. | 12-29-2011 |
